London is fear-struck and Scotland Yard is baffled by a series of strange murders plaguing the city; stories of the atrocities by crime author and journalist Edmond Bancroft (Michael Gough) scoff at for the Yard for conclusions missed. Along with his assistant Rick (Graham Curnow) Bancroft runs a private "Black Museum" filled with murder and torture devices. "Its titillating blend of nasty, unconventional murders and gimmickry made it a natural box office hit," writes DVD Drive-In of this 1959 feature—which is really and truly not for the faint of heart. That same year brought The Headless Ghost, in which three American exchange students go on a day trip to the supposedly haunted Ambrose Castle, decide to spend the night to investigate, and meet the ghost of the Fourth Earl of Ambrose.
